摘　　要：服务组合目前已成为业界研究的热点,它为组织间应用集成提供了一种新的解决方案。在完全开放的Internet环境中,组合服务需要Web服务事务处理机制来保证其可靠性,而Web服务事务处理需要一种异常处理机制的支持。针对节点故障引起的异常给出多种异常处理策略,对其进行形式化描述,并给出了异常处理的算法。最后在此基础上提出一个可定制补偿操作及相关补偿规则的灵活的组合服务事务异常处理模型,并对其实现。Composing services has become a hotspot ofresearch in both academia and industry. Anewblueprintforresolvingapplication integration between organizations is provided. In a totally opened Internet environment, composite service needs web service transaction to ensure its reliability, while web service transaction needs the support ofmeehanism for handling exception. Several strategies is offered which are described formally for handling exception on computing node, an algorithm for the handling of exception is given, at last a flexible model for handling exception of composed web service transaction is brought forward and realized.
